27. DECREASE IN OFF-PEAK ELECTRICAL ENERGY DEMAND BY AGROINDUSTRIES DUE TO PHOTOVOLTAIC SOLAR GENERATION
ABSTRACT The largest energy losses and voltage variations from electricity suppliers occur at times of peak demand. Daytime peaks are mainly influenced by large industrial and commercial consumers. The installation of photovoltaic systems without energy storage to supply part of the demand can contribute to stabilize the voltage and reduce losses. These and

29. Solar photovoltaic energy applied to ferroalloy industry
Abstract The Brazilian ferroalloy industry faces a highly competitive scenario in the foreign market. Among the key factors to determine the price of its products, electric energy stands out as one of the main inputs. So, the possibility of energy being unavailable or having high prices causes a direct impact in the ferroalloy chain. On the other hand, the r

33. Generation of Photovoltaic Solar Energy. Evaluation of the Demand Curve with the Insert of Grid-connected Photovoltaic Power System at CINDACTA II, Curitiba-PR, Brazil.
ABSTRACT Unlike some countries, Brazil has a predominantly hydraulic energy matrix, a clean and renewable source. But, in recent years, both the non-renewal of the normal volumes of water in the reservoirs and the lack of consciousness in the consumption of water and energy have placed the country in a critical state of energy supply leading to many intensiv

35. Analysis of shifting and reduction of the demand peak with the inserting of photovoltaic systems in the Neoville’s Headquarters of Federal University of Technology - Paraná Curitiba Campus
ABSTRACT Photovoltaic solar energy is increasingly present in the urban environment through the distributed generation. This kind of generation is characterized by the installation along the distribution network feeders, in low or medium voltage, and contribute to provide energy near the point of consumption. In this sense, this study aims to analyze the dem
